Specification of Letters Patent. patented Aug', 22, 1.922.

Application led April 2, 1920. Serial No. 370,874..

To @ZZ @07m/1a tmaf/ concern Be it known that we, 'RICHARD S; SiLvIs and .li-rnonomi Evans, citizens of the United States of America, residing at Rock Island, in the county, of Rock island and State of illinois, have invented new and useful improvements in Automatic Feeds, of which the following is a specification.V

This invention relates to improvements in automatic fluid feeding devices and has for an object the provision of means for maintaining predetermined quantity of oil, or other liquid in a vessel or receptacle.

Another object is the provision of a liquid supply tank or container, which is pro vided with a novel arrangement ot air controlled discharge means, jlor discharging its contents into a vessel or receptacle, the amount of liquid within theV latter governing the admission of air into the container, so as to automatically regulate the flow.

ifinother object is the provision of a novel arrangement inlety discharge valve tor the tank or container, so that when the inlet valve is opened to till said tank, the outlet valve will automatically close, so that the admission of air during the filling operation will not cause 'the discharge of any oi the contents of the tank.

lWith the above and other objects in view, the invention also includes the following novel features and details of construction, to be hereinafter more `fully described, illustrated in the accompanying drawings and pointed out in the claim hereto appended.

In the drawings Figure 1 is a side elevation of the invention.

Figure 2 is a plan view of the same.

Figure 3 is a central vertical sectional view showing the valve in position for filling the tank.

Figure 4 is a similar view with the valve in position for discharging.

Figure 5 is a horizontal sectional view through the tank or container.

Referring specifically to the drawings, wherein like characters of reference denote corresponding parts throughout the several views, the reference character 10 lindicates a supply tank or container, in which is contained the liquid to be supplied to a vessel or receptacle 11.

The invention contemplates `means for maintaining predetermined quantity of liquid, such as oil, water or the like, within `the vessel `or receptacle 11, and for this purpose the tank or container 10 has eX- tendmg vertically therethrough a pipe 12, the said pipe being preferablyv reduced as shown at 13 and connected to a vessel or receptacle 11 byl means of a coupling member 14. The pipe 12 extends upward tothetop of the receptacle and has connected thereto and communicating therewith, the

small flared end of a funnel-like member. 15

which extends upward through the :tunnel shaped member 15, is a valve20, which isy adapted to engage the seat 16,'the valve being so spaced upon the rod 18 that when the upper valvevis seated,.the lower valve will be unseated and vice versa. Secured to the upper extremity of the stem 18 is a handle 21 and surrounding this stem between the handle and a cross member 22 carried by the funnel shaped member is a coil spring 23, whose office is to seat the valve 2O and unseat the valve 19.

Located within the pipe 12 adjacent the top of the tank 10 is a series of openings 24, the purpose of which is to permit of the passage of liquid from the funnel shaped member 15 through the pipe into the tank 10, the handle 21 being depressed so as to unseat the valve 20, which is then disposed below the opening 24 to permit of this operation. Also formed in the pipe 12 adjacent the bottom of the tank, is a plurality or'J openings 25, which, when the valve 19 is unseated will permit of the passage of liquid 'from the tank 10-through the receptive portion adjacent to the pipe, to the vessel or receptacle 11.

Extending from the horizontal portion 26 of the pipe connection between the tank or container 10 and the vessel or receptacle 11, is a pipe 27, the'latter extending upward through the bottom of the receptacle into junta-position with the pipe 12, the top of said pipe 27 being open and disposed above the point to which the tank is filled, this point being determined through the use of a gauge 28.

yExtending from the point of connection Nw we. t.

i like-memberil WillL pass through the open-v ing 24 into theztanlnktlie yfilling operation of the pipes 26S-and 27, is a short relatively sniall pipevr 29, `establishing communication with the atmosphere 'fromthe interior of the pipe, for the purpose of supplying. `air thereto.

ln the operation of the invention, the

tank or container is "lilledf to the proper point by depressing the handlevQl.andwun-Y seating the valve 2O and seating the valve 19, Whereirom liquid poured vinto the funnel continuing until the Avessel or receptacle-*1l has aialsoffbeenillecl.
